Numerical and Experimental Study of Volumetric Particle Tracking Velocimetry in a Spatial and Temporal Domain
A hydraulic system was setup to generate a laminar flow in a cylinder tube. The flow is measured by the VPTV system for the purpose of demonstration. Fluorescent particles were employed to trace the fluid motion. An argon-iron laser was employed as the illumination system. The tube is immersed in a …

Numerical approximations of coupled forward-backward SPDEs with applications
… FBSPDE, the finite element method in the spatial domain leads to approximations by finite-dimensional forward-backward stochastic differential equations (FBSDEs) in the temporal domain. We then approximate the solution of FBSDE by some existing machine learning schemes. Strong convergence results …

Path manipulation strategies for rendering dynamic environments.
… bidirectional path tracing to reuse paths in the temporal domain. Defined as an apparatus of sampling and reuse strategies, path manipulation reconstructs the subpaths that compose the light transport paths and addresses the restriction of static geometry commonly associated with Monte Carlo light …

The Syntax of Temporal Interpretation in Embedded Clauses
… I argue that verbs in embedded clauses are temporally interpreted by being bound to the temporal arguments of AspP and VP in the matrix clause. I build up this claim by proposing that (i) Reichenbach’s relation of association can be expressed in terms of Binding Theory in the syntax, (ii) …

Qualitative representation and reasoning for spatial and spatio-temporal systems
… by identifying the main challenges facing the domain of QSRR, namely, the trade-off between expressiveness and efficiency and the trade-off between the completeness and soundness of the approaches. Towards facing the first challenge, a representation formalism is proposed for spatial objects of …

Multi-fidelity strategies for lean burn combustor design
… CFD simulation methodology is proposed, based on temporal domain decomposition, and further developed into a novel time-parallel co-Kriging based multi-fidelity design strategy requiring only a single CFD simulation to be setup for various fidelities. The performance and confidence assessment of …

A contextual analysis of definite and indefinite interpretations of tense
… In a discourse, times denoted by tenses and temporal adverbials are added to the context as salient. There may be multiple time intervals that are contextually salient, and these are available for the interpretation of subsequent temporal elements. That is, they may work as an antecedent of …

On Interference Management for Wireless Networks
… Specifically, we study IA in three different domains: spatial domain, spectral domain, and temporal domain. In the spatial domain, we study IA for multi-hop MIMO networks. We derive a set of simple constraints to characterize the IA capability at the PHY layer. We prove that as long as the set …
